Here are the four AO (.ant) models described on the above page
converted to AutoEZ (.weq) format, with the AO variable names used in
Brian's models converted to AutoEZ variables:

The original .ant files are included just for reference. AutoEZ can
read .ant files, with some restrictions; for these four it took a bit
of post-processing to clean things up.
For the first model ("Enhanced OWA") here are comparisons of Gain and SWR:

Folks who enjoy messing around with antenna modeling may wish to use
the AutoEZ optimizer in an attempt to improve on the design goals that
Brian mentioned. That may or may not be possible! :-)
